The occupational hazards associated with laser materials processing are reviewed. Industrial laser materials processing users were surveyed and the nature and scope of use were defined. Tabulated sales projections for industrial laser applications over 8 years are presented. Numbers, types and applications of laser use are given. Processes and materials for which laser applications are outlined. Types of lasers used for various operations, breakdown of laser types, wavelengths for the most common laser types, laser safety measures, and accidents reported also are given. General safety practices are discussed. A study on the degradation of polymers by carbon-dioxide lasers is described. The respiratory hazards of particles from laser interactions with metals are discussed, and tabulated data is included on respirable particles produced by various materials and on the weight per laser pulse of captured material. Safety considerations, potential hazards, and recommended safety practices are described. The authors conclude that hazardous gases can be produced in carbon-dioxide cutting of plastics. Sufficient quantities of respirable particulates are released during ruby laser drilling of metals to constitute a hazard. Proper ventilation is required for laser material processing systems to reduce these hazards.
